Although equal in power to other facets of the rich cultural ferment of modern Russia that have profoundly influenced Western civilization—such as painting, literature, drama, and politics—the authentic legacy of twentieth-century Russian philosophy has until recently been eclipsed by Soviet ideological dominance. Of the important philosophers drawing upon the characteristically Russian synthesis of Ancient Neoplatonism, German Idealism, and Byzantine spirituality, Sergei Bulgakov is outstanding, and his work has important implications for our contemporary thinking about the relationship between humanity and nature in an age of environmental crisis. Overcoming the objectivist stance toward nature consolidated by Descartes and ensconced by Kant, Bulgakov anticipates not only many existential and phenomenological thinkers in the West—especially Heidegger—but also current ecological sensibilities, by showing the ontological status of humanity and nature as profoundly interconnected, especially through his understanding of nature as “household.” Beyond this, he elucidates a normative, “thoesophianic” character of nature corresponding to Plato’s “world soul,” the Renaissance natura naturans, and Heidegger’s “divinely beautiful nature” which is best revealed not by science and technology, but by the aesthetic and contemplative energies of a humanity whose essential interconnection with nature is shown most profoundly by means of this mode of revealing itself
